Since iPad, Apple’s best selling product, led a trend of Tablet PCs, other manufacturers have accelerated the development and launch of Tablet PCs. LEDinside, a research division under TrendForce, indicated that LED application requirement for Tablet PC has improved, and average brightness specification has increased by over 20 percent compared to before. Additionally, LED shipment grew, too. It is estimated that LED shipment will rise to 1.3 billion in 2011 from 380 million in 2010, around 3.5 times in growth rate.
